Self-locking type strand pulling auxiliary device for prestressed steel strands

Abstract

The invention relates to the technical field of steel strand pulling, and discloses a self-locking type strand pulling auxiliary device for prestressed steel strands. The self-locking type strand pulling auxiliary device for the prestressed steel strands comprises a bottom plate, two vertical plates are fixedly connected to the left side of the upper end of the bottom plate in a front-back symmetrical manner, the opposite sides of the two vertical plates are rotatably connected with a same reel through a rotating shaft, and a steel rope is wound on the reel; a motor shell is fixedly clamped tothe outer walls of the vertical plates, a driving motor is fixedly connected into the motor shell, an output shaft of the driving motor is fixedly connected with a connecting block, one end of the rotating shaft penetrates through and extends out of the vertical plates, and a connecting groove matched and connected with the connecting block in a clamped mode is formed in the one end of the rotating shaft; two fixing frames are fixedly connected to the left side and the right side of the upper end of the bottom plate, and a same guide cylinder is fixedly connected to the inner walls of the fixing frames through a plurality of connecting rods. The self-locking type strand pulling auxiliary device for the prestressed steel strands has the advantages that a steel rope can advance at a constant speed to be accurately sent out, strand pulling of the steel strands is facilitated, and actual use is facilitated.

Description

technical field [0001] The invention relates to the technical field of steel strand threading, in particular to a self-locking beam threading auxiliary device for prestressed steel strands. Background technique [0002] In the prestressed construction technology of post-tensioned bridges, the problem of prestressed steel strand penetration is an important factor affecting the quality of prestressed construction. The traditional prestressed steel strand threading technology usually adopts two threading methods: manual threading and mechanical threading; the maximum threading length of artificial threading is 70m, and the ultra-long prestressed artificial threading is laborious and laborious, and as the bellows As the number of strands increases, the difficulty of threading also increases. [0003] The current steel strand threading device is very inconvenient to operate, affects the threading efficiency, and is not convenient for practical use. Contents of the invention ...
